Multiplayer games will work between Android TV devices and other Android devices, like tablets.

(In a later section of the keynote, Google Play product manager Ellie Powers said those Google Play services for developers are getting an upgrade that includes the ability to save game progress in the cloud.)

A good start, maybe. But it’s nothing that will have the console gaming establishment shaking in its boots.

When Amazon unveiled its own set-top box, the Fire TV, it called gaming an added “bonus” to the box’s core media features. This invited some pyrrhic sniffing from the likes of Ouya, the much-hyped Android-based gaming box that fizzled after launch last year.

The only Android TV games mentioned at I/O, by contrast, were a platformer called Leo’s Fortune and the Android version of EA’s NBA Jam. It’s early yet, and I’m sure we’ll hear about more games (and projects like Razer’s Android TV microconsole) in time, but the emphasis on other Android TV features like voice control tells us gaming is also something of a “bonus” here.

So, what gives?

Gaming dominates on mobile devices, accounting for some 90 percent of all revenue on Google Play, according to analytics firm App Annie. The multi-billion-dollar question is how important the convenience of gaming on the go is to that dominance.

Once you plunk games built on top of a mobile operating system into the living room, can they compete with the deeper libraries on users’ Xboxes, PlayStations and Wiis? Or, to reach those mobile gamers who don’t call themselves “gamers,” can they compete with movies and TV on the big screen?

The fact that the Ouya’s top game only sold 7,000 copies would suggest “no.” But that’s one data point. And for better or worse, Android TV doesn’t seem to be designed to offer any clarity.
